I've encountered deadlock in qemu during some stress testing. The test is making snapshots, committing them and constantly quering for block job info.What is the exact command you used for triggering the block-commit? Was it via direct HMP or QMP, or indirect via libvirt?
Via libvirt.
Were you trying to commit the active layer?
No. Commit was to intermediate file. I'm aware that libvirt does not support active layer commit yet.
Plus, judging from backtrace, hang seems to be deep inside qemu. The VM is unresponsive after this.
